Does NDK 2.23 support both IPv4 and IPv6 simultaneously?

Hi all,

    I am developing on TM4C129X Development board with TI-RTOS 1.20.00.28 and TI-NDK 2.23.00.00, CCSv5.5.0.00077.

    I am finding if TI-NDK 2.23.00.00 supports both IPv4 and IPv6 simultaneously in one network application.

    There are 4 ethernet examples: Tcp/Udp Echo IPv6/IPv4.

    In Tcp Echo IPv4 example, I tried to set Global.IPv6 = true in tcpEcho.cfg file and it still worked well. But when trying to set Global.IPv6 = true in udpEcho.cfg, it seems that the udpEcho application cannot get IP address from DHCP server any more. Then I tried to set static IP address for the board ( Add Ip.address = "192.168.1.148"; Ip.mask = "255.255.255.0"; Ip.gatewayIpAddr = "192.168.1.1"; Ip.domainName = "abc.net"; to file udpEcho.cfg)
 but this did not help, I couldn't ping to the board from my PC.

    In file tirtos_1_20_00_28\products\ndk_2_23_00_00\packages\ti\ndk\config\package.xs, I see that libs are linked depends on Global.IPv6 value.

Do you know if I can enable both IPv4 and IPv6 in my network application?

Thanks in advance,

Viet Hoang.
